IPC: H01L21/28
Filed: 1995-06-15
Abstract: PURPOSE: To decrease the number of steps in the fabrication of a thin film transistor provided with a silicide layer on the source and drain regions. CONSTITUTION: A silicifiable metal film 26 is deposited on the upper surface of a native oxide deposited on the surface of a thin semiconductor layer 25 and an ion barrier layer 27a of photoresist is formed by rear surface exposure on a gate electrode 22 and a gate line 23 formed on the upper surface of metal film 26. When ions are implanted, a silicide layer 28 is formed by the ion implantation energy on the surface of thin semiconductor layer 25 except the region beneath the ion barrier layer 27a. Subsequently, the ion barrier layer 27a is removed along with the unnecessary parts of metal film 26, silicide layer 28 and thin semiconductor layer 25 except the device regions thereof followed by the removal of metal film 25 on the channel region.  In this regard, no step is required for removing the native oxide on the surface of thin semiconductor layer 25 and the ion barrier layer 27a can be formed of photoresist only through the rear surface exposure.

Title: Plasma treating apparatus
Inventor: KATO HISAYUKI
IPC: H01L21/205
Filed: 1986-07-23
Abstract: PURPOSE:To enhance the treating speed of the formation of a thin film and the like and to improve the quality of a film to be formed and the like, by providing an electrode at the outside of a plasma stream toward a semiconductor substrate. CONSTITUTION:Electrons in plasma have large magnetic moment and react with the gradient of the intensity of the diverging magnetic field from a magnetic coil 4. The electrons are accelerated toward a holder 6. At this time, an ion source 1 is electrically insulated from the holder 6. Therefore the electrons, which are accelerated toward the holder 6, generate a negative space, and ion species are drawn out of a plasma forming chamber 1 so as to neutralize the potential in the sapce. Meanwhile, radicals in the plasma reach the upper surface of a semiconductor substrate 5. Chemical reaction is yielded on the semiconductor substrate 4. A thin film is formed on the semiconductor substrate 4. Thus the ion species and the electrons are deflected so that they are not directed to the semiconductor substrate, and plasma damage can be avoided. Therefore, the quality of the film can be improved.

Title: Method for diagnosing abnormal bearing for press machine and its device
Inventor: YONEYAMA TAKAO
IPC: G01M99/00
Filed: 1996-07-02
Abstract: PROBLEM TO BE SOLVED: To diagnose bearing failure of a press machine accurately by evaluating an AE signal detected from the press machine. SOLUTION: An AE signal is detected from press machines 1 and 2 through an AE sensor 3. The number of issues of AE signal which is detected during non-pressing and pressing operations is computed by a noise/bearing failure judgment part 7. A bearing failure evaluating part 8 judges according to the computation output of the part 7 whether the detected AE signal is noise or it is detected from a bearing failure part. Further, when it is caused by bearing defect, the part 8 judges the degree of failure. The judgment result is indicated by an indicator 9 in the outside. Thus, since whether the AE signal is generated from noise or bearing failure part is discriminated, erroneous diagnosis can be prevented and bearing failure be also detected accurately.  Further, the AE signals detected during non-pressing and pressing operations are compared, that is, failure status of bearing is judged, based on physically generated phenomenon, so that the state of bearing failure (degree of abnormality) can be judged accurately.
